Snow.

I've been having a blast riding in the snow this winter. Having proper gear to combat the cold has been a godsend. My typical layering goes like this:

Top:
1. Under Armour "cold" baselayer.
2. Louis Garneau merino wool long sleeve jerseyish thing.
3. Flannel shirt.
4. Sweatshirt.
5. Windbreaker.

Bottom:
1. Underwear.
2. Under Armour "cold" baselayer.
3. Jeans.

Pearl Izumi lobster claw gloves and Smartwool socks.

It's not perfect, but it's what I have available to me, and it works well for up to about 20 miles.

Anyway, took a detour today through the woods, which was incredibly fun but super difficult with the completely wrong bike, hah.
